A new trailer from Battlefield 3 shown today at Gamescom features 64-player combat on the Caspian border multiplayer map in DICE's upcoming military shooter sequel. The clip has some vehicular action and finally shows off some jet combat from the game. The embedded version follows.

If you don't want to play that sort of map you could easily filter for only 64 player conquest maps (control point), and get maps like the one in this video. As for server map rotation, that's set by whoever is running the server, but no one is going to switch between 32 and 64 player maps.

Was custom map rotations a feature in BFBC2? I never played it on the PC but with the 360 I don't believe you had any control over the rotation. You could search for servers running a specific map but once that round ended it was off to whatever other map was up.

I know BF2 offered this level of control, I just don't know about this new version.
